A report on Photon, Wave–particle duality, Electron and Light
A photon is an elementary particle that is a quantum of the electromagnetic field, including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force.- Photon
Like all elementary particles, photons are currently best explained by quantum mechanics, and exhibit wave–particle duality, their behavior featuring properties of both waves and particles.- Photon
Like all elementary particles, electrons exhibit properties of both particles and waves: They can collide with other particles and can be diffracted like light.- Electron
Like all types of electromagnetic radiation, visible light propagates by massless elementary particles called photons that represents the quanta of electromagnetic field, and can be analyzed as both waves and particles.- Light
Electrons radiate or absorb energy in the form of photons when they are accelerated.- Electron
The word quanta (singular quantum, Latin for how much) was used before 1900 to mean particles or amounts of different quantities, including electricity.- Photon
Democritus (5th century BC) argued that all things in the universe, including light, are composed of indivisible sub-components.- Wave–particle duality
Einstein's "light quanta" would not be called photons until 1925, but even in 1905 they represented the quintessential example of wave–particle duality.- Wave–particle duality
Deceleration of a free charged particle, such as an electron, can produce visible radiation: cyclotron radiation, synchrotron radiation and bremsstrahlung radiation are all examples of this.- Light
De Broglie's formula was confirmed three years later for electrons with the observation of electron diffraction in two independent experiments.- Wave–particle duality
In his 1924 dissertation Recherches sur la théorie des quanta (Research on Quantum Theory), French physicist Louis de Broglie hypothesized that all matter can be represented as a de Broglie wave in the manner of light.- Electron

The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material.
Because a low-frequency beam at a high intensity does not build up the energy required to produce photoelectrons, as would be the case if light's energy accumulated over time from a continuous wave, Albert Einstein proposed that a beam of light is not a wave propagating through space, but a swarm of discrete energy packets, known as photons.
Study of the photoelectric effect led to important steps in understanding the quantum nature of light and electrons and influenced the formation of the concept of wave–particle duality.
